You will still be able to unlock the achievements just fine. This is to prevent griefing of the world.
This world has been designed in a way for both online & offline play.When using these areas, you can close the gates to stop the mobs from escaping. There are quite a few achievements that have designated areas to spawn mobs in.However, if you do wear armor, this negates the invincibility, and you can take damage. You're invincible in this world, so you don't need to wear any armor.Meaning that it may not unlock when it is supposed to. Acacia Signs are for achievements that are buggy in a negative way. Meaning you can perhaps unlock it earlier than intended. Birch Signs are for achievements that are buggy in a positive way. Jungle Signs are additional information or tips that can help you get the achievement. There are four different color signs you will see in the world: Oak Signs are for achievement names and descriptions, or info directly related to getting the achievement.
Here is the layout of the achievement land, and where the updates are: However, you can filter these updates on the achievement page by using the G rouping feature in the 'Filter' drop-down. The walkthrough follows this structure, so due to this, there may not be a DLC pack for each update on some variants. This world is structured to have a section for each update that had a specific set of achievements release in it.We will also post updates on it (like if we update the world for new achievements). You can also just have a friendly chat with other Minecraft achievement hunters. You can post feedback by reporting any bugs or issues with the world or posting any suggestions you would like to see added. If you are confused about something or need help, you can ask there. Before we get started on the hints and tips, we would like to mention that we have a discord server for the achievement world.
